NAME

       ipa-replica-install - Create an IPA replica

SYNOPSIS

   DOMAIN LEVEL 0
       ipa-replica-install [OPTION]... replica_file

   DOMAIN LEVEL 1
       ipa-replica-install [OPTION]...

DESCRIPTION

       Configures a new IPA server that is a replica of the server. Once it has been created it is an exact copy
       of  the  original  IPA  server  and  is  an  equal  master.  Changes made to any master are automatically
       replicated to other masters.

       To create a replica in a domain at domain level 0, you need to provide an replica file. The  replica_file
       is created using the ipa-replica-prepare utility.

       To  create a replica in a domain at domain level 1, you don't have to provide a replica file, the machine
       only needs to be enrolled in the FreeIPA domain first. This process of turning  the  IPA  client  into  a
       replica is also referred to as replica promotion.

       If you're starting with an existing IPA client, simply run ipa-replica-install to have it promoted into a
       replica.

       To promote a blank machine into a replica, you have two options, you can either run ipa-client-install in
       a  separate  step,  or pass the enrollment related options to the ipa-replica-install (see DOMAIN LEVEL 1
       CLIENT ENROLLMENT OPTIONS). In the latter case, ipa-replica-install will join  the  machine  to  the  IPA
       realm automatically and will proceed with the promotion step.

       If  the  installation  fails  you  may  need to run ipa-server-install --uninstall and ipa-client-install
       before running ipa-replica-install again.

       The installation will fail if the host you are installing the replica on exists as a host in  IPA  or  an
       existing replication agreement exists (for example, from a previously failed installation).

       A replica should only be installed on the same or higher version of IPA on the remote system.

OPTIONS

   DOMAIN LEVEL 1 OPTIONS
       -P, --principal
              The  user  principal which will be used to promote the client to the replica and enroll the client
              itself, if necessary.

       -w, --admin-password
              The Kerberos password for the given principal.

   DOMAIN LEVEL 1 CLIENT ENROLLMENT OPTIONS
       To install client and promote it to replica using a host keytab or One Time Password, the host  needs  to
       be  a member of ipaservers group. This requires to create a host entry and add it to the host group prior
       replica installation.

       --server, --domain, --realm  options are autodiscovered via DNS records by default.

       -p PASSWORD, --password=PASSWORD
              One Time Password for joining a machine to the IPA realm.

       -k, --keytab
              Path to host keytab.

       --server
              The fully qualified domain name of the IPA server to enroll to.

       -n, --domain=DOMAIN
              Set the domain name to DOMAIN.

       -d, --realm=REALM_NAME
              Set the IPA realm name to REALM_NAME.

       --hostname
              The hostname of this machine (FQDN). If specified,  the  hostname  will  be  set  and  the  system
              configuration will be updated to persist over reboot.

   DOMAIN LEVEL 0 OPTIONS
       -p PASSWORD, --password=PASSWORD
              Directory Manager (existing master) password

       -w, --admin-password
              Admin user Kerberos password used for connection check

   BASIC OPTIONS
       --ip-address=IP_ADDRESS
              The IP address of this server. If this address does not match the address the host resolves to and
              --setup-dns  is not selected the installation will fail. If the server hostname is not resolvable,
              a record for the hostname and IP_ADDRESS is added to /etc/hosts.  This this  option  can  be  used
              multiple  times  to  specify  more  IP addresses of the server (e.g. multihomed and/or dualstacked
              server).

       --mkhomedir
              Create home directories for users on their first login

       -N, --no-ntp
              Do not configure NTP

              Do not automatically redirect to the Web UI.

       --ssh-trust-dns
              Configure OpenSSH client to trust DNS SSHFP records.

       --skip-conncheck
              Skip connection check to remote master

       -d, --debug
              Enable debug logging when more verbose output is needed

       --dirsrv-config-file
              The path to LDIF file that will be used to modify configuration of dse.ldif during installation of
              the directory server instance

   CERTIFICATE SYSTEM OPTIONS
       --setup-ca
              Install and configure a CA on this replica. If a CA is not configured then certificate  operations
              will be forwarded to a master with a CA installed.

       --no-pkinit
              Disables pkinit setup steps

       --skip-schema-check

   DNS OPTIONS
       --setup-dns
              Generate  a  DNS  zone  if  it  does  not exist already and configure the DNS server.  This option
              requires that you either specify at least one DNS forwarder through the --forwarder option or  use
              the --no-forwarders option.

       --forwarder=IP_ADDRESS
              Add  a  DNS  forwarder to the DNS configuration. You can use this option multiple times to specify
              more forwarders, but at  least  one  must  be  provided,  unless  the  --no-forwarders  option  is
              specified.

       --no-forwarders
              Do not add any DNS forwarders. Root DNS servers will be used instead.

       --auto-forwarders
